Poco F6 Pro underwater camera test: natural light performance, AquaExposure score, and available cases. Read before you buy!
Hi everyone, this is Benjamin. Today, we're taking a look at a new device that's generating buzz: the Poco F6 Pro. In the field, we're always looking for the right balance. A phone that can handle itself, one that doesn't let you down at the first sign of trouble. The Poco F6 Pro arrives with some promises, especially in terms of its camera. But the real question is how it performs once underwater, in natural light. Does it have what it takes to capture the magic of the underwater world without artificial enhancements? We're going to break it down together, away from the marketing specifications. What matters is the result you get in your hand, after the dive. Experience shows us that numbers on paper don't tell the whole story. It's real-world usage that makes the difference, especially when you're submerged. So we're going to test its limits, its strengths and weaknesses, to give you a clear and unbiased opinion.

Ideal Profile: The Poco F6 Pro is aimed at the occasional diver who wants a versatile smartphone for everyday use and some underwater photos without breaking the bank. It's perfect for you if you're new to underwater photography and prioritize ease of use. This isn't a professional-grade device, but it can work well for capturing vacation memories. It requires compromises, especially in terms of photo transfer speed and heat management. If you're looking for a backup solution for taking photos in natural light, it could be an option. However, don't expect miracles. You need to understand its limitations before using it underwater.
The Poco F6 Pro features a 50MP main sensor with an aperture of f/1.6. On paper, this sounds good. However, the actual size of the sensor and the quality of the lenses are what truly matter. The 1/1.55" sensor is decent, but not exceptional. It allows for capturing a reasonable amount of light, but it doesn't compete with giants like the Vivo X100 Ultra and their Zeiss optics. The latter operate in a different league with much larger sensors. With the Poco F6 Pro, you will get usable images, especially if there is plenty of natural light. However, don't expect the same depth of field or sharpness as dedicated cameras or high-end smartphones designed for photography. It's a good starting point, but it's important to be realistic about expectations.
For more details: The Poco F6 Pro features a 50MP main sensor (1/1.55", 1.0µm, f/1.6), an 8MP ultra-wide angle lens (f/2.2), and a 2MP macro lens. The Vivo X100 Ultra, X200 Pro, and X100 Pro stand out with their Zeiss optics and significantly larger sensors.
The ability to photograph in RAW format is a major advantage for post-production in underwater photography. It gives you incredible flexibility to recover details in the shadows or highlights, and to adjust the white balance. The Poco F6 Pro, like most recent Android smartphones, allows you to capture RAW files. This is a good point. However, the quality of the RAW file will depend heavily on the initial processing of the sensor. Some phones, such as Huawei devices running HarmonyOS, have limitations with third-party applications like Blackmagic Camera, which directly impacts the quality and management of the RAW file. With the Poco F6 Pro, you should be able to work on your images, but the richness of information contained in the file will not be the same as that of a larger sensor. This is a compromise to consider.
To learn more: Most modern Android smartphones support the RAW format. Be aware of alternative operating systems like HarmonyOS (Huawei P60 Pro / Mate 80 Pro), which may limit access to advanced camera applications and affect the quality of the RAW files.
Storage isn't just about the amount of gigabytes. It's also about the speed at which you can transfer your photos and videos after a dive. And that's where the Poco F6 Pro shows one of its weaknesses. It uses USB 2.0, which means transfer speeds of 480 Mbps. That's slow, very slow, especially if you've filled your memory card with RAW files and 4K videos. Imagine having to wait for hours to empty your phone after a day of diving. This is a key point to consider for your workflow. Devices like the Vivo X100 Ultra or the Honor Magic V3, with their USB 3.2 (10 Gbps), offer a much smoother experience. The Poco F6 Pro's Wi-Fi 7 can compensate somewhat for wireless transfers, but for large volumes, a cable remains king. And in that regard, the Poco F6 Pro is lagging behind.
For more information: The Poco F6 Pro and the Poco F7 Ultra are equipped with a USB 2.0 port (480 Mbps). In comparison, the Vivo X100 Ultra, X200 Pro, X100 Pro, Honor Magic V3, Huawei P60 Pro, and Mate 80 Pro benefit from USB 3.2 (10 Gbps). The Poco F6 Pro supports Wi-Fi 7.
Heat management is a major challenge for any smartphone sealed in a waterproof casing. Water is an excellent heat dissipator, but the casing itself provides insulation. The Poco F6 Pro, like many high-performance phones, can get hot. Overheating can lead to performance drops, unexpected shutdowns, or even damage the device. We've seen cases like with the Nothing Phone 2, which has a transparent back and heats up quickly. Conversely, a Motorola Edge 50 Fusion, with its plastic or leather back, manages heat better over time. With the Poco F6 Pro, it's important to be vigilant. Prolonged photo or video sessions can cause problems. Remember to take breaks between dives to allow the device to cool down. This is often an overlooked aspect, but it can ruin a photography outing.
For further information: Thermal dissipation is critical in phone casings. Some materials, such as plastic/leather (Motorola Edge 50 Fusion), can offer better thermal insulation than glass or transparent backs (Nothing Phone 2). Foldable phones (Honor Magic V3) are particularly sensitive to heat at the hinge.
Battery life is always a concern when diving. You can't recharge underwater! The Poco F6 Pro has a respectable battery size, but underwater photography and especially video are very energy-intensive. With the screen on, the sensor active, and image processing running, all of this drains the battery. For a day with multiple dives, it's likely you'll need an external battery pack between dives, or a fully charged phone before each outing. The good news is that fast charging is often present in these devices, which can help recover some power on the surface. But the real issue is managing your consumption and not being caught off guard. Always plan for extra capacity.
For more information: Underwater photography and videography heavily drain the battery. Proper energy management and a full charge before each dive are recommended.
Before each diving session, remember to check your external battery. Use our portable battery comparator tool (/tools/battery-comparator) to choose the right power bank for your dive equipment and desired battery life.
Autofocus is your best friend underwater. The light changes rapidly, subjects move, and you need a fast and accurate focus. The Poco F6 Pro is equipped with multi-directional PDAF autofocus and OIS (optical image stabilization). This is a solid configuration that should allow you to capture most scenes without too much difficulty. Compared to phones that require manual focusing, like some Huawei models, this is a clear advantage. However, the speed and accuracy of the AF can vary depending on the underwater lighting and contrast. In low-light conditions or with subjects that have little contrast, it may show its limitations. Test it in real-world conditions before embarking on important photo shoots.
For more details: The Poco F6 Pro features a multi-directional PDAF autofocus and optical image stabilization (OIS). Some devices, such as the Huawei P60 Pro and Mate 80 Pro, may suffer from manual or limited autofocus.
Without a waterproof housing, no underwater photography is possible. The Poco F6 Pro, despite its IP53 rating (splash resistance), is absolutely not designed for submersion. You will need a dedicated housing. The good news is that there are universal IP68 housings available that can accommodate phones up to 6.9 inches, which includes the Poco F6 Pro. Brands like WRTBS or ONEFLOW offer such solutions. The key here is to carefully check the compatibility of the physical or touch controls through the housing. Some universal housings may be a bit generic and not offer perfect ergonomics. For high-end models like the Vivo Ultra, specific housings like the Divevolk Platinum are often necessary. For the Poco F6 Pro, you will find options, but pay attention to the quality of construction and access to essential functions. It's the interface between you and your phone underwater, so it must be reliable.
For more information: The Poco F6 Pro has an IP53 certification (resistance to splashes, not immersion). Universal IP68 waterproof cases are available for phones up to 6.9 inches. Some specific devices (e.g., Vivo Ultra) require dedicated cases (e.g., Divevolk Platinum). The availability of cases for models like the Honor Magic V3 may be very limited.
As we have seen, a waterproof case is essential. For the Poco F6 Pro, you should opt for universal cases. Brands like ONEFLOW or WRTBS offer models compatible with the device's size. The key point is to check access to the buttons and the responsiveness of the touchscreen underwater. Some cases offer lever or button systems that replicate the phone's controls. This is what you should prioritize for a good experience. Also, make sure to check the maximum depth rating. Never compromise on the safety of your device. A waterproof case is your lifeline underwater.
The Poco F6 Pro is a good companion for occasional dives. However, its USB 2.0 port can be a bottleneck for a fast workflow. If you take many photos or videos, allow time for the transfer. Wi-Fi 7 can help, but for large files, a cable remains the most reliable method. Remember to clear your phone's storage regularly. Thermal management is also something to watch out for. Avoid excessively long sessions and let the device cool down between dives. A good workflow involves anticipating these limitations so you're not caught off guard.
The Poco F6 Pro is a good smartphone, but it has its limitations when it comes to underwater photography. The optical quality is decent, but it doesn't compete with the top players on the market. Data transfer is slow. Heat management requires attention. These are not deal-breaking flaws, but points to keep in mind so you won't be disappointed. The real question is whether these compromises are acceptable for your usage. If you're looking for a device for taking casual photos in natural light, it might suffice. However, if you're aiming for perfection, you'll need to consider higher-end options.
The Poco F6 Pro is positioned in a very competitive price segment. This is one of its major strengths. For a controlled budget, you get a high-performance smartphone for everyday use and capable of underwater photography. The cost of the waterproof case will be added, of course. But the total investment remains reasonable for beginners or for occasional use. It's a device that offers good value for money for those who don't want to spend a fortune on a dedicated underwater camera.
The Poco F6 Pro is a decent smartphone for underwater photography in natural light. It doesn't revolutionize the genre, but it gets the job done. Its key strength is its affordability. For a reasonable budget, you get a device that can accompany you underwater. You will have to deal with slow data transfer and thermal management that needs monitoring. But if you are an occasional diver or just starting out in underwater photography, it can be an excellent entry point. It allows you to capture beautiful memories without breaking the bank. For those who demand more, you'll need to look elsewhere. But for many, it represents a good compromise. It's a device that will allow you to get familiar with the basics of underwater photography before potentially investing in more specialized equipment.
